When I just have to convert a PDF to ePub, it needs to be added to library. Is there any way to convert it using calibre's converter without adding it to library? (Because it takes a while to add a file; which I don't want to keep in my library.)

Addition to context menu in explorer is highly required.

You can use the ebook-convert.exe command line tool to convert without adding to the library.
